ABSTRACT. 



Notes on the Growth and Development of a Specimen of a 

 South-Australian Battarea. By J. G. 0. Teppek, E.L.S, 



[Eead 17th June, 1009.] 



In April 1900 the specimen in question was received from 

 Miss IJna A. Wai-e, of Dalkey, 17 miles north of Adelaide, in the 

 " Mallee Scrub "of dwarf Eucaliiptus. It consisted of a fully- 

 developed Battarea from base to pileus, with a solid, heavy, tuber- 

 like mass attached. The specimen was shown on 1st May, 1900, 

 at a meeting of the Eoyal Society of South Australia (Trans, xxiv. 

 p. 171). A few days later spores were abundantly shed, and the 

 specimen bedded in sand and cov^ered with a bell-glass, and for 

 nearly a mouth it continued to develope in height. It was again 

 shown to the E. Society of South Australia on 6th June, when 

 the following dimensions were noted : — 



Total height from base to summit . . 235 mm. 



Pileus, diameter 42 ,, 



Stipes, at summit 12 „ 



5, 75 mm. below the summit . . 20 „ 



Peridium whitish when fresh, irregularly hemispherical and 

 smooth, except some slight irregular furrows. 



The specimen was handed to Dr. M. Holtze, F.L.S., Director 

 of the Adelaide Botanic Garden, and is there preseiwed in the 

 Herbarium. No other specimen has been recently found, but it 

 has been suggested that it may belong to Battarea phalJoides, 

 Dicks. The other Australian species known are B. Miielhriana, 

 Kalchb., from Torke's Peninsula, and B. Teppcriana, Ludw., from 

 N.W. Victoria.
